Technical field
The present invention relates to a kind of wear-resisting, the antifatigue compression roller with many material couples structure, application engineering bionics principle scientific design transition zone and cushion and consider the Performance Match of storeroom between roll body and wearing layer, improve anti-heavily stressed abrasive wear and the stress fatigue damage capability of compression roller, belong to Materials Science and Engineering field.
Background technology
Roll squeezer is the novel concrete grinding equipment grown up middle 1980s, has energy-efficient feature, is applied to cement producing line that classification breaks up and can economizes on electricity 30%-50%, improve the production efficiency more than 50% of subsequent ball milling machine.The operation principle of roll squeezer is that material feeds above roll squeezer two roller, brought between the compression roller of synchronous axial system in opposite directions continuously, under the effect of high-strength press stress, extruding and comminuting matter, make it become material cake that is closely knit, flat, that be full of microcrack and discharge from machine.The core component of roll squeezer is compression roller.Subject violent heavily stressed abrasive wear and stress fatigue destruction in the compression roller course of work, the wear-resisting and fatigue resistance difference of roll surface has a strong impact on cement and normally produces, and extremely manufacturer and user pay attention to always.For compression roller roll surface wear-resisting technology, domestic and international each large cement equipment company all drops into a large amount of funds and energy is studied, and successively develops one piece casting type, overall built-up welding formula, the bushing formula of built-up welding, hard alloy stud formula, sectional type and sintering cemented carbide formula etc.Wherein monoblock cast, overall built-up welding belong to earlier technique.Hard alloy stud formula and sintering cemented carbide formula, because of strong to the sensitiveness of foreign matter in material or because involving great expense, be not widely used.Sectional type roll surface, due to stressed irrationality, was namely denied after 1996.At present, consider from variant factors such as the reasonability of wear design and use, maintenance and replacings, built-up welding edge nested structure thinks that strong adaptability, combination property are best.The bushing formula roll surface of built-up welding achieves being separated of compression roller roll body and roll surface wear-resisting layer, can use different materials and process, meet the comprehensive mechanical property of compression roller roll body and the needs of roll surface wear-resisting performance respectively.Compression roller surface structure form affects highly significant to its wearability.Produce wearing and tearing and must possess two key elements, i.e. pressure and relative sliding simultaneously.Pressure needed for comminuting matter be by determine by the performance of comminuting matter, immutable, reduce material in extrusion process with the relative sliding of roll surface, be reduce wearing and tearing, extend the effective way in compression roller roll surface life-span.Rational surface structure morphological parameters is large to the occlusion angle of material, makes material fall into roller gap more steadily balanced, alleviates and eliminates the uneven wear of roll surface, keeping stable equipment operation, improve extruding efficiency and grinding quality.
The subject matter that current built-up welding bushing formula roll surface technology exists is that the chemical composition of roll body material and roll surface wear-resisting layer and performance exist larger difference, the compatibility that material is mutual and associativity poor, concentrate producing larger stress at faying face place again while raising roll surface wear-resisting layer material wearability, reduce the bond strength of roll body material and surface wear-resistant layer, wearing layer large area is caused to be peeled off, result be complete machine energy resource consumption large, reduce mill efficiency and quality, present " exerting oneself not efficient ".Therefore, how to improve the wearability of roll squeezer core component press roll surface wearing layer and the bond strength with roll body storeroom thereof, extend the service life of compression roller, improve utilization rate of equipment and installations, green manufacturing is implemented at cement industry, promoting recycling economy development, is researcher inescapable responsibility and long-term and difficult task.
Summary of the invention
The object of this invention is to provide a kind of wear-resisting, the antifatigue compression roller with many material couples structure, application engineering bionics principle scientific design transition zone and cushion and consider the Performance Match of storeroom between roll body and wearing layer, improve anti-heavily stressed abrasive wear and the stress fatigue damage capability of compression roller.
A kind of wear-resisting, antifatigue compression roller with many material couples structure of the present invention adopts the design of many combinations of materials, and compression roller is coupled to form by roll body, transition zone, cushion, wearing layer and roll surface form.Compression roller adopts many combinations of materials to design and the design of roll surface morphological parameters is bionical new thought by researching and proposing structure and the friction behavior of organism material.By biological as research discoveries such as desert lizard, intertidal zone shellfish, Rapana venosa and chitons to some, organism surface has excellent wear-resisting and fatigue resistance to be the functionally gradient material (FGM) structure that forms with the multilayer different hardness material of its body surface and in body surface form, to show multiple dimensioned structure have closely related.The body surface of desert lizard (Xinjiang rock lizard) forms duricrust supporter by the cutricular plate of outside, cuticula, comparatively soft connective tissue is filled in duricrust inside, the functionally gradient material (FGM) structure of this multilayer different hardness material composition, external constraint internal material, under the effect of axial compression load, internal material, at multi-direction pressurized, can delay longitudinal cracking during its pressurized, improve the elastic working performance of operational phase, larger plastic deformation can be born; Inside can delay and avoid outside prematurely cripling to occur simultaneously, makes inner and outer system have higher bearing capacity, generally all higher than the independent bearing capacity sum of inside and outside composition of composition system.Blood clam belongs to Bivalvia, and life of dwelling is buried by battalion, and in the husky process of brill, certainty rub with water, sand, the functionally gradient material (FGM) structure that body surface is made up of four layers of different material, and body surface configuration of surface presents longitudinal rib shape.This special functionally gradient material (FGM) structure of blood clam and body surface form have important function to its antiwear characteristic.In conjunction with the service behaviour of roller press squeeze roll, wear mechanism and failure mode, a kind of wear-resisting, the antifatigue compression roller with many material couples structure is thus proposed according to many material couples structure of organism surface.
The job specification of compression roller requires that roll body has good combination property, and roll surface requires to have good anti-wear performance.Compression roller roll body adopts the medium carbon low alloy steel forging such as 42CrMo, 40Cr, this type of material has good mechanical property, but weldability is poor, directly very easily crack at its surface overlaying high-abrasive material, in order to avoid cracking, need preheating surfacing, and the high steel alloy roll body intensity that will make of preheat temperature declines, therefore can not at steel alloy roll body surface directly build-up wear-resistant material.By at the softer transition zone of roll body surface overlaying one deck, built-up welding preheat temperature is lower, both can not affect the mechanical property of steel alloy roll body, also can not crack.The low-carbon low-alloy steel that buffer layer material selects moulding process good.Composition, the structure and properties difference of transition zone and wearing layer material are comparatively large, and must there be a cushion centre, makes the Composition and property of the two there will not be interface abruptness.Cushion adopts that intensity is higher, the high-alloy steel materials that can play excellent support effect to wearing layer, and its effect to absorb the energy that wearing layer passes over, and prevents wearing layer from absorbing comparatively macro-energy and occur crackle and fatigue, causes initial failure.Compression roller outermost layer is wearing layer and morphemic stratum.According to the actual working conditions of compression roller, transition region thickness h1=10-15mm, buffer layer thickness h2=10-15mm, wearing layer thickness h 3=15-20mm; Roll surface form is striated, roll surface morphological parameters determines according to the shape and size of grinding material that (material presents irregularly shaped, average diameter 20-30mm), design principle be exactly reduce material in extrusion process with the relative sliding of roll surface, large to the occlusion angle of material, make material fall into roller gap more steadily balanced, by this principle: streak height H=5-10mm, width of fringe M=10-15mm, fringe spacing L=5-15mm, high (H)/wide (M) ≯ 0.8.
